Book excerpt: The quasi-axisymmetric stellarator (QAS) concept offers a promising path to a more compact stellarator reactor, closer in linear dimensions to tokamak reactors than previous stellarator designs. Concept improvements are needed, however, to make it more maintainable and more compatible with high plant availability. Using the ARIES-CS design as a starting point, compact stellarator designs with improved maintenance characteristics have been developed. While the ARIES-CS features a through-the-port maintenance scheme, we have investigated configuration changes to enable a sector-maintenance approach, as envisioned for example in ARIES AT. Three approaches are reported. The first is to make tradeoffs within the QAS design space, giving greater emphasis to maintainability criteria. The second approach is to improve the optimization tools to more accurately and efficiently target the physics properties of importance. The third is to employ a hybrid coil topology, so that the plasma shaping functions of the main coils are shared more optimally, either with passive conductors made of high-temperature superconductor or with local compensation coils, allowing the main coils to become simpler. Optimization tools are being improved to test these approaches.

Available in PDF, EPUB and Kindle. Book excerpt: This monograph describes plasma physics for magnetic confinement of high temperature plasmas in nonaxisymmetric toroidal magnetic fields or stellarators. The techniques are aimed at controlling nuclear fusion for continuous energy production. While the focus is on the nonaxisymmetric toroidal field, or heliotron, developed at Kyoto University, the physics applies equally to other stellarators and axisymmetric tokamaks. The author covers all aspects of magnetic confinement, formation of magnetic surfaces, magnetohydrodynamic equilibrium and stability, single charged particle confinement, neoclassical transport and plasma heating. He also reviews recent experiments and the prospects for the next generation of devices.

Download or read book Stellarator Approach to Fusion Plasma Confinement written by and published by . This book was released on 1985 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The stellarator is a toroidal fusion plasma confinement device with nested magnetic flux surfaces. The required twist of the field lines is produced by external helical coils rather than by plasma current, as in a tokamak. Stellarator devices are attractive fusion reactor candidates precisely because they offer the prospect of steady-state operation without plasma current. In the last few years the excellent results achieved with currentless stellarator plasmas of modest minor radius (10 to 20 cm) at Kyoto University (Japan) and the Max Planck Institute (West Germany) have made the stellarator second only to the tokamak in its progress toward fusion breakeven, with temperatures T/sub e/, T/sub i/ approx. 1 KeV, Lawson products n tau approx. 2 to 5 x 1012 cm−3.s, and volume-averaged beta values approx. = 2%. The Advanced Toroidal Facility (ATF), now under construction at Oak Ridge Natioal Laboratory (ORNL) and scheduled to operate in 1986, represents a significant advance in stellarator research, with a plasma major radius of 2.1 m, an average minor radius of 0.3 m, and a magnetic field of 2 T for 5 s or 1 T at steady state. ATF replaces the Impurity Study Experiment (ISX-B) tokamak at ORNL and will use the ISX-B heating and diagnostic system.

Available in PDF, EPUB and Kindle. Book excerpt: Humans do not live by bread alone. Physically we are puny creatures with limited prowess, but with unlimited dreams. We see a mountain and want to move it to carve out a path for ourselves. We see a river and want to tame it so that it irrigates our fields. We see a star and want to fly to its planets to secure a future for our progeny. For all this, we need a genie who will do our bidding at a flip of our fingers. Energy is such a genie. Modern humans need energy and lots of it to live a life of comfort. In fact, the quality of life in different regions of the world can be directly correlated with the per capita use of energy [1.1–1.5]. In this regard, the human development index (HDI) of various countries based on various reports by the United Nations Development Programme (UNDP) [1.6] (Fig. 1.1), which is a parameter measuring the quality of life in a given part of the world, is directly determined by the amount of per capita electricity consumption. Most of the developing world (~5 billion people) is crawling up the UN curve of HDI versus per capita electricity consumption, from abysmally low values of today towards the average of the whole world and eventually towards the average of the developed world. This translates into a massive energy hunger for the globe as a whole. It has been estimated that by the year 2050, the global electricity demand will go up by a factor of up to 3 in a high growth scenario [1.7–1.9]. The requirements beyond 2050 go up even higher.

Book excerpt: 'Holgate guides us expertly and with a deft touch along the journey towards the holy grail of unlimited energy for all.' - JIM AL-KHALILI 'What is nuclear fusion? In clear and accessible language, this book explains the basics and the hope for the future. A valuable addition to the Hot Science series.' - JOHN GRIBBIN Could the Sun hold the key to a future of clean energy? Since the 1950s, scientists have attempted to harness nuclear fusion - the process that creates the Sun's energy - to generate near-limitless amounts of electricity. But the fact that we still have no fusion power plants is testament to the complexities of the challenge. Now, the deepening climate crisis means that researchers around the world are in a race to create a mini-Sun here on Earth. The glittering prize is an energy source that emits no greenhouse gases and could solve energy equity and supply issues at a stroke. Sharon Ann Holgate, a former Young Professional Physicist of the Year, tells the compelling story of the ongoing scientific quest for a revolutionary new era of green energy production.

Download or read book Fun in Fusion Research written by John Sheffield and published by Newnes. This book was released on 2013-02-20 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses the fun side of the quest to develop fusion energy—a modern equivalent of the hunt for the Holy Grail. After more than 70 years of research, despite great progress, the goal has not been realized. Do you have to be crazy to love quests like this? Not really, but you do have to have an unshakeable optimism. Through humorous anecdotes, and accessible yet detailed scientific discussion, this book illuminates the enjoyment of scientific research through an account of fifty years working on fusion energy development. The anecdotes bring out the human side of research, in which innovative and sometimes egocentric scientists create both clever and nutty experiments. Among the many stories within are witchcraft at Harwell, shocking experiences, entertaining talks, and the wit of top scientists such as Marshall Rosenbluth. Above all the book highlights the significant advances made in developing practical fusion energy and the promise for an exciting future with the National Ignition Facility and International Thermonuclear Experimental Reactor. This book will be of interest to physicists as well as other students and researchers in the scientific and wider communities. Shows the exciting and fun aspects of science research Author has spent 54 years working in the area, offering key insights on the history of fusion Clear, detailed explanations of fusion energy are supplied, helping non-science readers understand the area
